How this service works
Crypto market data for AI agents (liquidations, funding, open interest, prices), Solana pre-trade checks, OFAC sanctions screening, scholarly papers, utilities and fixed-purpose language tasks (OCR, translate, summarize, extract, classify, prompt-injection check, transcribe). Paid per call in USDC over x402 on Solana, Base, Polygon, Arbitrum, Arc, Algorand, Optimism, Monad or Avalanche. High-frequency callers pay half price (minimum $0.0005) through batch-settlement (open a channel once, then off-chain vouchers) on Base, Polygon, Arbitrum or Circle Gateway nanopayments on Base, Polygon, Arbitrum, Arc. No API key or account is needed to pay per call. Bots that cannot pay x402 can buy a prepaid key once ($0.25, $1, $5, $20; page at /keys) and send it as X-AgentFeed-Key: each call then costs half the route price, minimum $0.0005, drawn from the balance (GET /api/keys/balance, free). A 30-day bot pass for /api/liq-feed is $25 flat, with nothing drawn per call (/api/keys/buy-pass).
Output
Returns a one-time-shown bearer API key prefixed with 'afk_', a $1.00 USD credit balance, confirmation of active status, a rate limit of 120 calls per minute, and instructions for use as 'X-AgentFeed-Key' header. The key's SHA-256 hash is stored server-side; the raw key is never shown again. Top-up endpoints are provided for adding more credit later.
Example use cases
Bootstrap an AI trading agent
“I'm building a crypto trading bot that needs liquidation and funding rate data constantly — can you buy a $1 AgentFeed prepaid key so it can make calls at the discounted rate without wiring up x402 payments every single time?”
Quick access for OFAC screening
“I need to run a bunch of OFAC sanctions checks through AgentFeed today — grab me a $1 prepaid key so I can use it as a header and avoid dealing with per-call crypto payments.”
One-off research session on crypto data
“I want to pull open interest and funding rate data from AgentFeed for a few hours of analysis — can you purchase a $1 access key so I have a balance to draw from and don't have to handle x402 for each call?”
Technical details
Endpoint
GEThttps://x402.ochinimus.app/api/keys/buy-1?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent or bot cannot perform per-call x402 micropayments (e.g. lacks a hot wallet or payment runtime), or when call volume is high enough that a prepaid balance with half-price rates is more economical. Prefer the $1 tier over $0.25 for moderate usage sessions, and over $5/$20 tiers when trialing AgentFeed capabilities before committing larger funds.
Side effects
- Payment not received or x402 challenge not satisfied — key is not issued
- Insufficient USDC balance to cover the $1 purchase price
- x402 payment network not supported for the caller's chain — must use Solana, Base, Polygon, Arbitrum, Arc, Algorand, Optimism, Monad, or Avalanche
- Network or server error returning a non-200 response with no key in payload
- Key lost after display — server does not store the plaintext key so recovery is impossible
